Bock ABSTRACT: Collapsible basket in the formof a rectangular tray especially useful in harvesting of fragile cropssuch as leaf tobacco. Bottom wall of rigid plywood has side and endwalls of composite structure, including panels of plastic laminate andcanvas, the canvas serving to hinge sidewalls to bottom and, optionally,being extended to form flexible top closure flaps. End walls havetriangular plastic laminate panels secured to canvas and defining thefold lines along which canvas may be folded inwardly to collapse emptybasket. End walls have supplemental plastic laminate flaps separatelyhinged to bottom wall to be swung into reenforcing position against theinner surface of the end walls when basket is erected, thereby holdingbasket in open position. Bottom wall has flanges on all four sidesextending beyond side and end walls will carry vertical loading whenseveral filled baskets are stacked for storage or transportation.

COLLAPSIBLE WEATHERPROOF TRAY OR BASKET FOR CROPS AND THE LIKE Thecollapsible basket of thepresent invention affords a relativelylightweight uncomplicated construction which, when erected into the formof a rectangular tray with or without the closure flaps, provides rigidand durable load bearing side and end walls which are set inwardly ofthe side and end edges of a rigid bottom wall. When filled with somefragile material, for example, vegetables or leaf tobacco the basket maybe stacked on top of other identical baskets with the load-bearing sideand end wall protecting the contents from crushing. Since the side andend walls are set inwardly from the outer edges of the bottom wallconsiderable latitude is afforded for stacking baskets in trucks forshipment to a processing area with assurance that the upper baskets inthe stack will not tilt into the lower baskets thereby damaging thecontents of the latter.

A particular feature of the present invention lies in the constructionof the end walls of the basket which are composites of a flexible sheetmaterial such as canvas and a relatively rigid material such as plasticlaminate. Plastic laminate in the form of a triangle with apex upwardlydisposed is secured to the canvas which is rectangular and in turnsecured to the end zones of sidewalls. The angularly disposed sides ofthe triangular plastic laminate panel define angular fold lines alongwhich the end walls may be folded to form inwardly disposed gussets whenthe basket is collapsed. Since such end walls would tend to foldinwardly at all times a supplemental plastic laminate panel is hinged tothe bottom wall of the basket so as to be folded upwardly intoreinforcing position holding the end walls from collapse and alsospanning the entire width and the entire depth of the basket so that thereenforced end walls will bear their share of vertical loading incident,for example, to stacking a number of the erected filled baskets forstorage or shipment.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of abasket embodying the form integral continuations of the canvas forming apart of the composite sidewalls l8 and 20.

When the basket 10 is filled the flaps 22 and 24 are folded over thecontents as shown in FIG. 3. An importantrequirement for baskets of thisgeneral type is that they should be capable of stacking several high fortransportation in trucks without danger of crushing the fragile contentsof the baskets in the lower levels of such stacks. From a considerationof FIGS. 1, 2 and 3 it will be observed that the rigid bottom wall 12 ofeach basket 10 is somewhat larger than the top opening defined by theend and sidewalls 18, 20, 22 and 24 to provide flanges which extendlaterally outwardly beyond each of the end and sidewalls. Therefore whena basket 10A is stacked upon the basket 10 as shown in FIG. 2 the endwalls 14 and 16 give vertical support to the basket 10A along lineswhich lie well inside the lengthwise dimensions of the bottom wall 12A.Also, as shown in FIG. 3 the sidewalls 18 and 20 give vertical supportto the basket 10A well within the lateral dimension of the bottom wall12A. Thus, considerable tolerance is afforded for inaccuracy of registryof an upper basket with one beneath it, whereby with reasonable care itcan be assured that the cor ners of upper baskets within a stack willnot tend to tilt into and crush the contents of baskets in the lowerpart of the stack.

DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to FIG. 1 thecollapsible basket 10 of the present invention is shown in erectedposition ready to be filled with a product such as vegetables. fruit,tobacco leaves or the like. The basket 10 comprises a rigid bottom wall12 made of a rugged water-resistant material such as exterior gradeplywood, end walls 14 and 16 and sidewalls I8 and 20, the end andsidewalls being made of a composite of flexible material such as canvasand relatively rigid sheet material such as a plastic laminate. Coverflaps .22 and 24 preferably are made ofa flexible material such ascanvas and as shown herein 16 are first folded inwardly and thesidewalls 18 and 20 will follow, as will be explained below, to lieflatwise upon the end walls and bottom wall 12.The top closure flaps 22and 24 are then folded inwardly towards one another to lie upon thesidewalls 18and 20.

An intermediate positionassumed by the basket 10 during collapse orerection for use is illustrated in FIG. 5 and constructional details ofthe basket are most clearly shown in FIGS. 6 through 9. Referring firstto FIG. 7 the sidewall 20 is made up of a sheet of canvas or similarflexible material 26 to which is laminated a relatively rigid generallyrectangular panel 28, preferably made of a plastic laminate the verticaldimension of which establishes the height of the wall 20. The canvas 26extends beneath the lower edge of panel 28 and terminates in a flangeportion 30 which is adhesively secured to the upper surface of theoutwardly extending portion of bottom wall 12. The canvas 26 thus servesas a hinge extending throughout the length of the sidewall 20.

The canvas 26 continues beyond the upper edge of plastic laminate panel28 to form the flexible top cover flap 24. Preferably the flap 24 is ofsuch length, extending transversely of the basket, as to cross thelongitudinal centerline of the basket so that it and the opposite flap22, which is of similar length, will overlap as shown in FIG. 7, thus toassure closing of the top of the basket 10, when desired. The centraledge of flap 24 terminates in a turned-back portion 32 enclosing a rigidmetal rod 34 (also see FIG. 6). The flap 22 also has a turned-backcentral edge 35 enclosing a rigid metal rod 36. The rod 34 and 36 notonly serve to rigidify :he overlapping edges of flaps 24 and 22 butalso, because the ends thereof rest on the end walls 14 and 16 when thebasket is closed, prevent other baskets or objects from depressing thetlaps 24 and 22 onto the contents.

The turned-back edges of flaps 24 and 22 may be secured by stitching orthe like. However, as will be described below it is preferred to use anadhesive material of sucl formulation as to form an extremely durablewaterproof bond throughout the turned-back area, thus to permanentlysecure the rigid metal rods. Appropriate adhesive material will bediscussed below.

The top cover flaps 24 and 22 may be omitted in any instance wherein anopen structure may be preferred. Without the cover flaps the basket maybe used as an open tray which is collapsible and stackable.

The sidewall 18 is the same in construction as the sidewall 20. Thus itcomprises a sheet of canvas 26A and a relatively rigid panel 28A (seeFIG. 6).

The end wall 14 is made up of a generally rectangular sheet of flexiblematerial such as canvas, which includes (see FIG. 5) a foldable centralportion 38 to which is laminated a triangular panel 40 of relativelyrigid material, such as a plastic laminate. The lower edge portion ofcanvas 38 is turned under the lower edge of panel 40 to form a flange 42which is adhesively secured to the top surface of the adjacent end ofbottom wall 12. Thus the triangular panel 40 is hingedly connected withthe bottom wall 12. The canvas 38 also is provided with side flanges 44(see FIG. 7) which are adhesively secured to the inner surfaces of thecanvas 26 and 26A respectively in sidewalls 20 and 18.

From a consideration of FIGS. 5 and 7 it will be apparent that the endwall 14, when in erected position, sets inwardly of the ends of thesidewalls 18 and 20 to which the end wall 14 is secured by side flanges44. Also, the end wall 14 sets inwardly I of the end of bottom wall 12to which it is secured by the flange 42. When the end wall 14 is'niovedtowards collapsed position, as shown in FIG. 5 the canvas panel 38 willfold along the sloping sides of triangular panel 40, thus to formgussets which will be substantially flat and will lie beneath thesidewalls l8 and which are automatically drawn downwardly when the endwall 14 is thus moved.

In order to facilitate such folding, without localized strain orwrinkling, the end wall canvas panel 38 is cut away at the lower cornersalong angularly disposed edges 46 which, for convenience, are extendedinto the adjacent flanges 42 and 44. Such cutting of the cornersprovides relief openings at secured canvas flanges 44A (see FIGS. 5 and6). The canvas panel 38A is cut away along sloping lines 46A to affordthe relief openings described above.

A particular feature of the present invention lies in the constructionof end walls 14 and 16 including the triangular panels 40 and 40A whichautomatically define the angular fold lines along which the end wallswill fold when pushed inwardly to collapse the basket. This assures thatthe end walls and sidewalls will fall into smooth flat relationshipwithout particular care or attention.

To hold the basket in erected position there are provided supplementalflaps 50 and 52 (see FIGS. 5 and 6) made of relatively rigid materialsuch, for example, as a plastic laminate. The flaps 50 and 52 are hingedto the bottom wall 12 just inside the end walls 14 and 16 respectively.As shown in FIG. 5 the supplemental flaps 50 and 52 are lying flatwiseupon the top surface of bottom wall 12, the position which the flapsassume when the basket is collapsed. In FIG. 6 the flap 52 is shownswung upwardly into operative position wherein it reinforces the endwalls 16. The flaps 50 and 52 may be hinged to the bottom wall 12 by ansuitable means but for the particular construction of the basket shownherein it is preferred to use strips of flexible material such as canvaswhich will be self-adjusting and extremely durable under the conditionsof use encountered in the harvesting of field crops, for example. Thus,as shown in FIGS. 7 and 9 the end wall 14 has a centrally locatedopening 54 cut through the triangular panel 40 and canvas 38 and throughthe flange 42 to accommodate a pair of canvas strips 56 which areadhesively secured to the upper surface of the bottom wall 12 in thearea exposed by the cutting away of the central portion of flange 42.The inner ends of hinge strips 56 are adhesively secured to the innersurface of the supplemental panel 50 thus to afford a hinge linesubstantially coinciding with the lowermost edge of the supplementalpanel 50.

The supplemental panel 52 for end wall 16 (see FIG. 6) is similarlyhinged by a pair of canvas hinge strips 58 which, in

turn are adhesively secured to the adjacent end portion of the bottomwall 12.

Both of the supplemental panels 50 and 52 have upper,

major portions which are of such width (as viewed in FIG. 8,

for example) as to snugly fit between the canvas portions 26 and 26A ofthe sidewalls I8 and 20. Thus, when moved to operative position as shownin said FIG. 8, for example, the supplemental panels 50 and 52 willserve to stretch the associated end walls 14 and 16 out flat andfrictionally engage the sidewalls so as to securely hold the basket inerected positron.

Preferably, the lower edge portions of supplemental flaps 50 and 52 aresloped upwardly as shown at 58 and 60 in FIG. 8 and 62 in FIG. 6 toprovide clearance therebeneath for accu mulations of earth, sand or thelike which otherwise might place undue strain upon the supplementalpanels 50 and 52 when they are moved to operative position. The centralvertical dimension of each of the supplemental panels 50 and 52 is such,allowing for the thickness of the associated hinge strips 56 or 58, asto afford a vertical load-bearing zone extending along a substantialportion of the width of the end walls 14 and 16. Thus, as viewed in FIG.6, for example, the upper edge of flap S2 lies substantially at the samehorizontal level as the upper edges of the sidewalls 18 and 20 while thelower horizontal edge portion of the flap 52 rests upon the hinge strips58 thus firmly pressing against the bottom wall 12.

The triangular end wall panels 40 and 40A preferably are provided with ahandhoie 64 and 64A respectively, of appropriate size and shape tofacilitate lifting and handling of the basket 10 when in erectedposition. Preferably, also, the handholes 64 and 64A are cut through thecanvas panels 38 and 38A to which the triangular panels 40 and 40A arelaminated. The supplemental flaps 50 and 52 as shown herein are notprovided with matching handholes and this construction is preferred whenthe basket is to be used for tobacco leaves or other products whichmight be damaged by the fingers of a person using the handholes. In suchinstances the end walls 14 and 16 and the associated supplemental flaps50 and 52 have sufficient flexibility to permit a persons fingers to beinserted through the handholes 64 and 64A and squeezed in between theinner surfaces of the end walls and the associated supplemental panels.

When the basket of the present invention is to be used solely inconnection with some crop or product which does not need protection fromcontact with the users fingers the supplemental panels 50 and 52 may beprovided with handholes (not shown) in such position as to fall inregistry with the handholes 64 and 64A when the basket 10 is in erectedposition.

If so desired the security of the closed filled basket 10 may beenhanced by a plurality of snap fastener elements 66 applied to thecover flaps 22 and 24 along the edge regions thereof which overlap whenthe basket is closed, as shown in FIGS. 7 and 8 for example. The matingparts of such fastener elements 66 are positioned on the lower surfaceof cover flap 22 and on the upper surface of cover flap 24 in theparticular illustrated embodiment inasmuch as flap 22 lies on top offlap 24 when the basket is closed. Obviously this may be reversed and ininstances Where fastener elements are not supplied the flaps 22 and 24may be overlapped in any sequence.

The fastener elements 66 may be any of the types of snap fastener whichare customarily used with canvas in tents, tarpaulins and the like.Alternatively other suitable types of seperable fasteners may be used,for example flexible fasteners of the hook-and-loop type sold under theregistered trademark VELCRO may be used by securing mating parts in theform of strips or tabs to the overlapping regions of the cover ilaps 22and 24.

As noted above it is preferred to secure various parts of the basket ofthe present invention together by the use of a suitable adhesive. To besuitable for such use an adhesive must form a very strong bond highlyresistant to peeling apart of the assembled elements under rough outdoorusage which includes exposure to sun and rain. Also, preferably, theadhesive should be one which is approved by regulatory authorities foruse in food containers. Adhesives of the water-based, latex emulsiontypes are available which meet all of the requirements established foruse in the present invention. A particular adhesive of the latter typeis sold by Swift & Company, identified as Swifts No. 4252 adhesive. Thisparticular adhesive has been used in the manufacture of fully usefulversions of the present invention. In those instances the plasticlaminate panels, such as the triangular panels 40 and 40A and thesidewall panels 28 and 28A were laminated to the canvas wall elements bythat adhesive. Also, the canvas flanges such as 30, 40 and 42 were sosecured to the bottom wall 12 and the flanges 44 were so secured to thecanvas elements 26 and 26A of the sidewalls and 18. Also, thesupplemental panel hinge strip 56 and 58 and the turned-back edgeportions 32 and 35 of flaps 24 and 22 were secured by this sameadhesive.
